Beyond the Classroom: Fostering Soft Skills in Pre-Professional LIS Organizations     

Emma J. Cobb  Jennifer Meixelsperger  Kadie K. Seitz 《图书馆管理杂志》2015,55(2):114-120

Are LIS graduates being adequately prepared to work in the information workplace? While students are absorbing valuable knowledge, library school curricula do not foster the essential soft skills students need to thrive in their post-graduate careers. However by being an active member of a graduate student organization, future LIS professionals can gain and hone effective soft skills, such as communication, initiative, curiosity, understanding, and the means to deal with mistakes, while adopting responsibilities that will all ultimately translate to success in the professional workplace, particularly in their first positions following graduation.  相似文献   

Gay On-Screen: The Relationship Between Exposure to Gay Characters on Television and Heterosexual Audiences' Endorsement of Gay Equality     

Bradley J. Bond  Benjamin L. Compton 《广播与电子媒介杂志》2015,59(4):717-732

The current study, grounded in the parasocial contact hypothesis, employed a survey of emerging adults to investigate the relationship between exposure to gay characters on television and heterosexuals' endorsement of gay equality. A positive relationship existed between exposure to on-screen gay characters and gay equality endorsement. The relationship was stronger for racial minority participants than for White participants, and for participants who had no or few interpersonal relationships with openly gay individuals than for participants who had more than three respective relationships. Results are discussed in terms of the parasocial contact hypothesis and television as an agent of social change.  相似文献

Enhanced single-cell printing by acoustophoretic cell focusing     

I. Leibacher  J. Schoendube  J. Dual  R. Zengerle  P. Koltay 《Biomicrofluidics》2015,9(2)

Recent years have witnessed a strong trend towards analysis of single-cells. To access and handle single-cells, many new tools are needed and have partly been developed. Here, we present an improved version of a single-cell printer which is able to deliver individual single cells and beads encapsulated in free-flying picoliter droplets at a single-bead efficiency of 96% and with a throughput of more than 10 beads per minute. By integration of acoustophoretic focusing, the cells could be focused in x and y direction. This way, the cells were lined-up in front of a 40 μm nozzle, where they were analyzed individually by an optical system prior to printing. In agreement with acoustic simulations, the focusing of 10 μm beads and Raji cells has been achieved with an efficiency of 99% (beads) and 86% (Raji cells) to a 40 μm wide center region in the 1 mm wide microfluidic channel. This enabled improved optical analysis and reduced bead losses. The loss of beads that ended up in the waste (because printing them as single beads arrangements could not be ensured) was reduced from 52% ± 6% to 28% ± 1%. The piezoelectric transducer employed for cell focusing could be positioned on an outer part of the device, which proves the acoustophoretic focusing to be versatile and adaptable.  相似文献   

Microfluidic sampling system for tissue analytics     

A. Hokkanen  I. Stuns  P. Schmid  A. Kokkonen  F. Gao  A. Steinecker  J. Budczies  P. Heimala  L. Hakalahti 《Biomicrofluidics》2015,9(5)

We have developed a microfluidics based sampling system for tissue analytics. The proof-of-concept of the sampling system was demonstrated by extracting lipid samples from tissue biopsies. The sample collection system consists of a disposable silicon based multiport microneedle integrated with polymer microfluidics. The polymethyl methacrylate polymer microfluidic chip has a 10 μl sample reservoir and actuation membranes for liquid pumping. A special automated robotic system was developed to control the positioning of the needle and the sampling procedure on preselected spots on the tissue. Real breast cancer tissue samples were used to test the feasibility of the sampling system. We successfully measured indicative cancer biomarkers from the tissue surface. Phosphatidylcholine and phosphoethanolamine were extracted from the tissue membrane with methyl tert-butyl ether solvent and detected by mass spectrometry. In the future, this tool could be used in characterization of preoperative biopsies and tumour tissues removed during surgery.  相似文献   

Tracking of physical activity in pubertal boys with different BMI over two-year period     

Triin Rääsk  Kenn Konstabel  Jarek Mäestu  Evelin Lätt  Toivo Jürimäe  Jaak Jürimäe 《Journal of sports sciences》2015,33(16):1649-1657

We examined the tracking of physical activity (PA) measured by accelerometers and subjective self- and parental reports in normal weight and overweight and obese pubertal boys over two-year period. In total, 156 boys with mean (±SD) age of 11.53 ± 0.76 at baseline and with mean age of 13.94 ± 0.74 at 2 year follow-up were studied. At baseline and approximately two years later, the boys completed self-report questionnaire and wore an accelerometer for seven consecutive days. On the basis of first year assessment’s body mass index (BMI), the children were grouped as normal weight and overweight and obese groups according to BMI cut-offs. Tracking correlations of objectively measured PA and subjectively measured PA were fairly similar across the 12–14 year-old-boys weight groups over two year period. Tracking correlations of objectively measured PA and subjectively measured PA were not significantly different over two-year period between both BMI groups. The results of the study show that pubertal boys objectively measured PA decreased over two-year period and so the boys started to be less active in their pubertal period.  相似文献   

The use of spatial manipulation to examine goalkeepers’ anticipation     

T.L. Woolley  K. Doma  J.D. Connor 《Journal of sports sciences》2015,33(17):1766-1774

This study investigated whether anticipation and search strategies of goalkeepers are influenced by temporally and spatially manipulated video of a penalty. Participants were clustered into three groups depending on skill: goalkeepers (n = 17), field players (n = 20) and control group (n = 20). An eye tracker was worn whilst watching 40 videos of a striker kicking to four corners of a goal in random order. All 40 videos were temporally occluded at foot-to-ball contact, and the non-kicking leg of 20 videos was spatially manipulated. Results showed that goalkeepers had significantly better predictions than the two groups with no differences between the two testing conditions. According to effect size, the percentage of fixation location and viewing time of the kicking leg and ball were greater for the goalkeepers and field players group than the control group irrespective of testing conditions. The fixations on the kicking leg and ball in conjunction with comparable predictions between spatially manipulated and control conditions suggest that goalkeepers may not rely on the non-kicking leg. Furthermore, goalkeepers appear to use a global perceptual approach by anchoring on a distal fixation point/s of the penalty taker whilst using peripheral vision to obtain additional information.  相似文献   

The Dutch motor skills assessment as tool for talent development in table tennis: a reproducibility and validity study     

Irene R. Faber  Maria W. G. Nijhuis-Van Der Sanden  Marije T. Elferink-Gemser  Frits G. J. Oosterveld 《Journal of sports sciences》2015,33(11):1149-1158

A motor skills assessment could be helpful in talent development by estimating essential perceptuo-motor skills of young players, which are considered requisite to develop excellent technical and tactical qualities. The Netherlands Table Tennis Association uses a motor skills assessment in their talent development programme consisting of eight items measuring perceptuo-motor skills specific to table tennis under varying conditions. This study aimed to investigate this assessment regarding its reproducibility, internal consistency, underlying dimensions and concurrent validity in 113 young table tennis players (6–10 years). Intraclass correlation coefficients of six test items met the criteria of 0.7 with coefficients of variation between 3% and 8%. Cronbach’s alpha valued 0.853 for internal consistency. The principal components analysis distinguished two conceptually meaningful factors: “ball control” and “gross motor function.” Concurrent validity analyses demonstrated moderate associations between the motor skills assessment’s results and national ranking; boys r = ?0.53 (P < 0.001) and girls r = ?0.45 (P = 0.015). In conclusion, this evaluation demonstrated six test items with acceptable reproducibility, good internal consistency and good prospects for validity. Two test items need revision to upgrade reproducibility. Since the motor skills assessment seems to be a reproducible, objective part of a talent development programme, more longitudinal studies are required to investigate its predictive validity.  相似文献   

Self-report vs. kinematic screening test: prevalence,demographics, and sports biography of yips-affected golfers     

Martin K. Klämpfl  Philipp B. Philippen  Babett H. Lobinger 《Journal of sports sciences》2015,33(7):655-664

The yips is considered a task-specific movement disorder. Its estimated prevalence, however, is high compared to similar neurological movement disorders, possibly resulting from previous studies’ restriction of samples based on skill level, and self-report bias. Alternatively, this high prevalence might be an indication of additional aetiologies, for example the influence of previously played racket sports. We estimated the prevalence of the putting yips across the skill range, using self-reports in one study and a screening test in a second study. We explored if previously played sports matter for the development of the yips. In study 1, yips prevalence (N = 1,306) and golfers’ sports biographies (n = 264) were examined via two online surveys, in which golfers indicated if they were yips-affected. In study 2, golfers (N = 186) putted in a standardised putting test while kinematic and performance measures were recorded. Prevalence was estimated via a kinematic threshold. Sports biographies (n = 119) were obtained via an online survey. Prevalence of currently yips-affected golfers was 22.4% in study 1 and 16.7% in study 2. In both studies, more yips-affected than unaffected golfers had experience in playing racket sports. Yips prevalence remained higher than previously estimated prevalence of other movement disorders but decreased when the whole skill range including professionals and novices was considered. Future studies should use the kinematic screening test instead of self-reports to detect the yips and further investigate the influence of previously played racket sports.  相似文献
